The Date of the Irvine-Eglinton Agreement

Introduction

FMG News no.12, sent to members electronically in June 2015, invited readers to submit solutions to a puzzle posed by Andrew B W MacEwen concerning the date of a bipartite agreement between the burgesses of Irvine and Brice of Eglinton, supposedly sealed in 1205. We received no responses, so here we summarise Mr MacEwen’s conclusions, which he sent to us before his death in 2015.
